BRICK-DIE.

SPECIFICATION forming part of Letters Patent No. 586,461, dated July 13,1897.

Application filed October 1, 1896.

T 0 (all whom it may concern:

Be it known that I, CLARENoE M. STEELE, of Statesville, in the county ofIredell and State of North Carolina, have invented a new and usefulImprovement in Brick-Dies, of which the following is a specification.

My invention is an improved brick-die having polished metal surfacesthrough which the clay is forced, forming itinto bars for the purpose ofmaking brick; and the invention consists in certain novel constructions,combinations, and arrangements of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my brick-die. Fig. 2is a transverse section on about line 2 2, Fig. 1. Fig. 3 is ahorizontal section on about line 3 3, Fig. 1; and Figs. 4 and 5 aredetail views.

The means for supplying the clay to the die and for receiving the barsdischarged therefrom may be of any desired construction.

The die is composed of the die-sections A A, the partition B, and theshell or casing C. The shell 0 is cylindrical and is provided at its endwith lugs G, perforated for the bolts 0 which secure the shell to theheads of the die-sections A. This shell has a steam-inlet D and anoutlet cl and is yovided with the threaded openings for the'stems of thevalves E, which valves are adapted to be turned by a suitable toolapplied to their outer ends, or they may be otherwise suitably turned.The valves operate to control the supply of lubricant to thedie-passages, as more fully described hereinafter.

The die-sections A A are formed with the passages a for the clay, suchpassages having polished surfaces and being open at both ends and at oneside, the latter being closed by the partition B, which fits and is heldbetween the die-sections.

At their ends the die-sections are provided with flanges A and A madecircular at a and a to fit the shell 0, and the flanges A being extendedat A forming heads for connection with the casing of the main portion ofthe machine.

The die-sections are connected together by the bolts A which bind themtightly against the partition, which projects at its edges between theedge of the die-sections. This par- Serial No. 607,570. (No model.)

tition is chambered and open at its side edges, communicating with thespace between the shell or casing and the die-sections, into which steamis supplied at D, so it will circulate around the die-sections andthrough the partition. The partition has at one end lugs or flanges,curved at 6 to fit in the outer end of the shell and has at its otherend lugs or flanges curved to correspond with the flange a and extensionA Inlets for oil or other suitable lubricant are provided at the outercorners of the die-passages at the inner end of the die, such inletsbeing controlled by the valves E, before dc-' scribed. lVithin the diesI provide cornerplates F, covering the lubricant-inlets and serving toprevent the clogging of the same, and also to secure a distribution ofthe oil upon the polished surfaces of the die-passage.

At its inner end the partitionBis extended beyond the end of thedie-sections and is brought to an edge to divide the clay as it passesto the two passages.

The circular shell is important in that it bears all the outward strainupon the dies.

My die is so constructed that it will form the greatest variety of layswith the least friction, and the several parts may be easily dressed outand polished and can be securely put together with the aid of only twobolts and cap-screws, and the circular case takes all the strain,therebeing no direct pressure against either bolts or set-screws.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A brick-die composed of die-sections, a chambered partition locatedbetween the sections and forming one of the sides of the die-orifices,and the casing or shell, a steamchamber surrounding said sections and10- cated between the casing or shell and the sections being providedWithin the casing or shell and communicating with the chamber in thepartition, substantially as shown and described.

2. A brick-die comprising the die proper having a partition chambered toreceive steam and the casing surrounding the die proper and forming asteam-space and means for supplying steam to said partition and casingsubstantially as shown and described.

3. The combination with the die-sections of a shell or casing encirclingand holding said sections together and forming a steamchamber aroundsuch sections the said sections forming the inner wall of thesteamchamber substantially as shown and described.

4. A brick-die comprising the die-sections having end flanges, thepartition-fitted between said sections and having end flanges coincidingwith those of the die-sections and the casing inclosing said sectionsand partitions substantially as shown and described.

5. The combination of the die-sections, the partition clamped betweenthe said sections and the shell or casing fitting around said sectionssubstantially as shown and described.

6. The combination of the die-sections and the intermediate partitionprovided at their ends with flanges formed to fit the shell or casingand the shell or casing surrounding such die and partition substantiallyas shown and described.

7. The combination in a brick-die of the die-sections, the partitionfitted at its edges between the said sections and devices connectingsaid sections and holding them to the partition substantially as shownand described.

8. The combination of the die-sections, the chambered partition open atits edges and fitting at such open edges between the edges of thedie-sections, means connecting said sections and the casing encirclingthe diesections and partition and forming a chamber in communicationwith the chamber of the partition substantially as shown and described.
